In particular, the introduction of sub-2 µm particles required an enlargement of the back pressure capabilities as well as the minimization of all system- and dead volumes. That is why the gain in efficiency by using smaller particles is closely related to the pump technology as we would like to demonstrate in the following.

It facilitates taking measurements in both dry, free-flowing bulk solids and in a wet dispersion unit. http://www.laboratory-journal.com/science/chemistry-physics/labwise-dynamic-image-analysis Mon, 09 Oct 2017 07:07:00 +0000 CRISPR/Cas9 Protein Delivery Technologies http://www.laboratory-journal.com/science/life-sciences-biotech/crisprcas9-protein-delivery-technologies The CRISPR/Cas9 system has emerged as a potentially game-changing tool for gene therapy. However efficient delivery of CRISPR components in mammalian cells is required for successful genomic editing. Different delivery formats with the ability to overcome issues connected with the use of viral, plasmid and RNA strategies have been developed, with protein-based CRISPR delivery being particularly promising. This review will cover advances in delivering Cas9 protein for gene editing.   Indroduction   http://www.laboratory-journal.com/science/life-sciences-biotech/crisprcas9-protein-delivery-technologies Fri, 06 Oct 2017 12:28:00 +0000 Molecular Scissors Revolutionize Plant Breeding http://www.laboratory-journal.com/science/life-sciences-biotech/molecular-scissors-revolutionize-plant-breeding The bacterial CRISPR/Cas system revolutionizes the possibilities of targeted genome modifications and thus enables unprecedented progress in plant breeding. The understanding of natural DNA repair mechanisms in combination with this highly specific, versatile and efficient molecular tool allows for both the precise introduction of mutations in DNA and targeted reshuffling of genomes. Such modifications of genetic information can no longer be distinguished from naturally occurring events.   http://www.laboratory-journal.com/science/life-sciences-biotech/molecular-scissors-revolutionize-plant-breeding Fri, 06 Oct 2017 08:48:00 +0000 Chiral Amines in Total Synthesis: The Biocatalytic Approach http://www.laboratory-journal.com/science/chemistry-physics/chiral-amines-total-synthesis-biocatalytic-approach Procedures for the efficient production of enantiopure amines are highly desired reactions in total synthesis in lab-scale as well for industrial applications.

Only with the use of photometers and defined and standardized color systems, the subjective visual estimation was replaced with an objective and accurate measurement. This measurement procedure attempts to describe a color using one or more numeric values. In this whitepaper you learn which methods can be applied and what the applications are. http://www.laboratory-journal.com/applications/color-measurement/photometric-color-measurement Wed, 27 Sep 2017 13:55:00 +0000 Webinar: Inline Sample Preparation – An Effective Tool for Ion Chromatography http://www.laboratory-journal.com/news/company-news/webinar-inline-sample-preparation-effective-tool-ion-chromatography Sample preparation in Ion Chromatography is connected to the chemical composition and the physical state of the sample at hand.

Nowadays, new plastic materials, which are environmentally friendly and bio-degradable, are calling for more and more attention. Meanwhile, the substituting plastic material should be cheap, easy to synthesize and recyclable while possessing comparable mechanical properties to conventional plastics.    http://www.laboratory-journal.com/science/material-science/mineral-plastic Wed, 27 Sep 2017 09:10:00 +0000 Amount of Water Influence Stem Cells Differentiation http://www.laboratory-journal.com/news/scientific-news/amount-water-influence-stem-cells-differentiation Adding or removing water from a stem cell can change the destiny of the cell, researchers have discovered in a new study published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). The research found that altering the volume of a cell changed its internal dynamics, including the rigidness of the matrix lining the outer surface. In stem cells, removing water condenses the cell, influencing the stem cells to become stiff pre-bone cells, while adding water causes the cells to swell, forming soft pre-fat cells. http://www.laboratory-journal.com/news/scientific-news/amount-water-influence-stem-cells-differentiation Wed, 27 Sep 2017 09:08:00 +0000 Storing Information at the Molecular Level http://www.laboratory-journal.com/science/chemistry-physics/storing-information-molecular-level Around 1900, it became possible to store information on magnetic wires and tapes, and this development finally paved the way for modern day computers. With the advent of personal computers and related devices, such as mobile telephones, our world has become highly technology-oriented and data storage has become digitalized. One of the challenges in the highly technological world that we live in is saving large amounts of information in the digital form. http://www.laboratory-journal.com/science/chemistry-physics/storing-information-molecular-level Wed, 27 Sep 2017 08:50:00 +0000 Human Antibodies from Dengue Patients Effectively Treat Zika Infection in Mice http://www.laboratory-journal.com/news/scientific-news/human-antibodies-dengue-patients-effectively-treat-zika-infection-mice Scientists have discovered that antibodies taken from patients infected with Dengue virus are effective in treating Zika infection in rodents. The team, led by researchers at Imperial College London and Washington University in St Louis, found that giving Zika-infected mice the antibodies was enough to treat the early stages of infection, and even protected unborn pups in pregnant animals. http://www.laboratory-journal.com/news/scientific-news/human-antibodies-dengue-patients-effectively-treat-zika-infection-mice Wed, 27 Sep 2017 08:32:00 +0000 Focal Molography: Holograms for Molecules http://www.laboratory-journal.com/news/scientific-news/focal-molography-holograms-molecules Scientists at ETH Zurich and Roche have developed a completely new method for the analysis of molecules in liquids on a chip. The possible applications of this technology are immense. It has the potential, inter alia, to revolutionise medical diagnostics. Much can be detected in blood or urine: viral illnesses, metabolic disorders or autoimmune diseases can be diagnosed with laboratory tests, for instance. But such examinations often take a few hours and are quite complex, which is why doctors hand the samples over to specialist laboratories. http://www.laboratory-journal.com/news/scientific-news/focal-molography-holograms-molecules Tue, 26 Sep 2017 08:44:00 +0000 Ricin Only Lethal in Combination with Sugar http://www.laboratory-journal.com/news/scientific-news/ricin-only-lethal-combination-sugar Researchers at the Austrian Academy of Sciences’ Institute for Molecular Biotechnology (IMBA) have discovered a means of immunising cells against the biological weapon ricin, as reported in the current issue of Cell Research. http://www.laboratory-journal.com/news/scientific-news/ricin-only-lethal-combination-sugar Wed, 20 Sep 2017 07:46:00 +0000 Qualitix - New Pipette Tip Programme http://www.laboratory-journal.com/products/micropipette/qualitix-new-pipette-tip-programme Socorex is pleased to announce the launch of its new Qualitix tip programme including an extended model selection covering most application requirements.
